To all whom #may concertar-' Y u Be it known that I, ARfrrrUn Bunnron, 'a citizenof the United Statee'residing vat Iittseld, in the. county of Berkshireand Statel of Massacliu'setts, have invented certain new vand useful Improvementsin Fuel' Savers,

of which the follovvingfisafspecification. Y

The present invention relatesto auxiliary draftattachments lfor furnaces, and the objectzsis to .provide V`a simplev and practical structure that maybe readily applied tol a furnace door and Will admita supplemental supply of air abovev the'fire for the purpose of securing more complete combustion of the gases and the iire.

In vthe accompanying drawings 2% ferred embodiment of the invention, illustrating the same mounted,

Figure 2 is a longitudinal sectional view on the line 2 2 .of Figure l,

Figure 3 is a front elevationxof a portion of the Vfurnace door, With the attachment in.

place,Vv Y c Figure l is a front elevation of said attachment,

Figure 5 is a view showingthe' vattachment shifted in order to allow an increased amount'of air supplied therethrough. f In the embodiment disclosed, a head is employed, comprising a cylindrical Wall 6.

andsubstantially flat bottom and top :Walls 7 and 8. The top :vvall'is providedrvithfa large number of perforations 9, preferably arranged in concentric/circles, though the arrangement is immaterial. furthermore provided with a laterallydis'- posed nipple 10 communicating with the internal chamber 11 of said head. f

A stem 12 isalso provided, this-stem tapering toward oneend, the smaller end 13 being cylindrical in form and detachably telescoping the nipple 10.'l VThe outer end of the stem is provided With a transverse Wall 14 having a substantially T-shaped opening therein, comprising a horiz'ontalslot 15 and a vertical opening 16 that preferably "opens into said slot. s

A holding bolt 17 is employed that is adapted to pass through the slot 15 and is Y provided with spaced washers 18 and 19.

Preferably the 'attachment is mounted on the inner side of a furnace door, a portion other products arising 'from similarl to Figure V3, but

ItV Will thus beY evident that air] .passing throughthe'opening 22-Will Vflow 1 l lthrough* the stem12. and be discharged' through the'perforations-upvvardly,with the Froml the foregoing, itV is thought that the Y Y construction, Voperation and many 'advan-v tages; of' the herein described invention will be apparentto those v skilled in the art, Without furtherdescription, and it will be under-V stood that various changes in the size, shape,

proportion and minor details of construction kvantages of fthe invention.

may be resorted towithout departing from .Y the spirit or sacrificing any ofthe vad'v Having thus fully deseribedrmyniyeanon, f' ,what I claim as new, and desireto vsecure byf'f' Letters vPatent, is

In combination with av furnace door having an air'inlet formed therei'ma fur- `I nace attachment for aiding combustion, com# -prising a fila-t hollo-W'head having its upper Y carrying saidYho-llow headl on its' smaller end;`

loof

thek shankof the kT may be alinedvvith the c air inlet. 2. In combination with a Vfurnace door having an air inlet formed therein, an at# tachment Vfor. aiding combustion comprising a'bolt mountedv insaid furnace door, a plate having a T-shaped slot formed therein ad- 4- justably'mounted on saidbolt sothat a porj tion of the slot may be alined with the'air,

inlet V in the furnace door, a tapering stem carried by saidplate, vthe largerend of the Vsame being adjacent the plate, and a flatv hollow head having its upper face perforated mounted on the smaller end of said stem.

3. In combination with furnace doors hav- 5 ing` aii` inlets formed therein, an attachment for aiding combustion comprising` a plate having an opening'formed therein, means for adjustably mounting said plate on the.

furnace door sol that the opening may be 10 alined with the air inlet, a tapering tubular stem carried by said plate, the larger-end being vadjacent the plate, and a hollow headv carried by theV stem, said head being perforated for directingy a current of air upward.

In testimony whereof, I 'ax my signature 15 in the presence of two witnesses.
